Why Choose the ABB S403P-C8 Miniature Circuit Breaker?
The ABB S403P-C8 is a high-performance 3-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit currents. As part of the ABB SMISSLINE TP S400P series, it combines current-limiting circuit protection with ABB's plug-in technology for efficient installation in commercial, industrial and critical power distribution systems.
The S403P-C8 features a Type C tripping characteristic and a rated current of 8 A. It uses a delayed thermal tripping mechanism for overload protection together with an electromechanical tripping mechanism for short-circuit protection, providing dependable protection for cables and connected electrical equipment.
With three protected poles and a rated ultimate short-circuit breaking capacity of 40 kA at 240/415 V AC according to IEC/EN 60947-2, the S403P-C8 provides robust protection for three-phase control, auxiliary and distribution circuits where high fault-current capability and convenient plug-in installation are required.
